Edinburgh B&B

I can't offer any help except to say that you need to mention how many rooms you actually need for these 10 people. Five? Three? I have a feeling not many B&Bs can accommodate a party of 10 people but I could very well be wrong. I was once before, in 1998.

We will probably divide up into 3 or 4 rooms.

We stayed at A-Haven townhouse hotel. It’s really a B&B. We took a bus from the airport to the station, then switched busses. The bus dropped us off right beside the B&B. It is not right downtown, but because the bus stop is on the corner by the hotel, it is very convenient. We bought a day bus pass every day and rode all over, including to Craigmiller castle and Rosslyn chapel. You can contact it via its website. The contact link on the site is at the bottom of the page.

Thanks Jaimeelsabio, I will check out your recommendation.

hmm, yes, me thinks that is a lot of people for a B&B to accomodate.
Have you checked out AirB&B?

have a look at this website, lots of good info there,
B&B's in Scotland tend to be pretty small places and may only have 3 or 4 letting rooms,Guest House will have more but are not big either.

Thanks for the recommendations.. Seven of us stayed in 1 room in our last visit which had enough beds but the one bathroom just about done us in! The grands are now teens and we have added 3 so we need more room(s), beds and baths. Thanks again.

There are some amazing rentals for flats on York Place across street from National Gallery, right on tram line from airport. Check out Air BnB for New Town flats with close proximity to tram line.

Traditional B&Bs wayyyy too expensive for that large of a group. You can do better renting one or two flats.
