Am I too early

I don't think you're too early but they may still be dealing with the challenges of this summer. Some people/businesses just don't prioritize emails (same with some people you know, right?) Keep at it. Depending on the website, some businesses have a "contact me" button that's separate from their email, that you could try. And at some point, check Google maps or another source to see if they went out of business and neglected to shut down their website and email.

It’s not too early to reserve accommodations this far in advance. You often will get the best pricing for doing so.

Paris and Lisbon are very popular destinations and hotels often book up completely. This can mean the property staff do not have to communicate with potential customers. You might try going to booking sites such as Booking.com or Hotels.com to see what rooms are available for four and then make a cancellable reservation. After making the cancellable reservation you can contact the hotel directly through the booking site to ask the questions you have. This may expedite getting you the answers you want from the properties you are considering.

Many hotels can be reached via an email address in the format info@hotelname.
These emails are received by the front desk staff, who will usually respond fairly quickly.

If your questions go beyond the scope of the front desk staff’s responsibilities, they will forward them to management. A response from management does indeed depend on the priorities that are set.

I booked my March Lisbon hotel back in April. So, it is not too early.

No email response after 2 weeks would be a big red flag for me. I often email hotels prior to booking and have always received responses within 24-48 hours.

Have you checked your “junk” email folder to see if the responses are in that folder?

Thank you all for your input. I did not hear from the hotels but did go ahead and make an online reservation for 2 rooms at Be Poet
Hotel in the Baixa area of Lisbon. what their site does not allow is to add a room so I had 2 make 2 reservations.
Has anyone stayed there?

I’m not familiar with that hotel but it has good reviews and the location is excellent. It is one minute away from the hotel where I stayed--Hotel Santa Justa. I liked the location so much that I will be staying there again next year. The only for me was the annoying restaurant workers.

From my trip report:

My hotel was located in the Baixa District, which was super convenient
as I was able to walk everywhere. But, the location came with one
negative—the restaurant workers!! The workers are out in the middle of
the streets, trying to get everyone who walks by to look at their menu
and come inside. You can get stopped by 10 different people in the
span of 2 minutes. Don’t even try to say, “Sorry, not hungry” because
that’s just the opening they are looking for. “Oh that’s ok, come
inside, have a coffee.” I found it best to not make eye contact and
just ignore them. Every once in a while, I’d say “no thanks.” The key
is to keep walking, do not stop.
