A family of for we enjoyed staying at Emilia's place. It has an interesting architecture and clever design decisions. Clean apartment with everything you need for an extended stay. Fast Internet connection.
Very convenient location, very close to the newer market. The most important sites are within walking distance.

Two things to be aware, small issues really:
The floor is very polished and if you're walking with socks only it may get slippery. We had to carry the 4yo from/to the upper bedroom because we forgot her rubber flip-flops.
The bedroom on the lower floor may get noisy in the night from the street noises. The upper bedroom is very quiet though, and we slept very well there.
