This is a great place to stay! It's located in a quieter part of the Old Town, not right on the main streets, which are much noisier.
The street it is on has some great restaurants, in particular a delicious Georgian and Mexican restaurant. Because it's in the Old Town, there are many restaurants, cafes, pubs, and other drinking/dining establishments all around.
The larger supermarkets are a bit of a walk, but that's no problem when you're walking in such beautiful surroundings. There are some small neighborhood markets very nearby.
It is very near the Staroměstská metro station, and there are tram lines within a few minutes walking distance in several directions.
The place was kept clean, and there was space provided in the fridge and kitchen for me to keep some food. The kitchen has everything you need if you plan to cook while staying here.
The hosts are quiet, and keep to themselves.
If everything above sounds like it suits you, I'm sure you'll enjoy staying here!
