The apartment is wonderful. It's super close to public transport (the metro is about a 5 minute walk and there's a bus stop right outside the door) and to many of the sights. It'd be hard to find a more centrally located place to stay. A 30 minute walk (or less) will get you to just about all the big sights. The apartment itself it well-equipped with everything you could need (full kitchen, towels, hair dryer, etc. and even a bottle of wine provided by the hosts), and the hosts were lovely, very helpful, and accessible. The only downside is that it's at the top of 5 sets of stairs, but it's good to work off some of the great food you'll be eating. Definitely would stay again.
