Loved our stay at Sofia's apartment. The location is just outside of the centre but the transport system is just so good that we found it a great base to stay.
It takes around 10-15 mins to walk to the metro station, so easy.
The apartment is spotlessly clean, warm and cosy with everything you could need, with the exception of a TV.
Lovely quiet and safe neighbourhood to stay in. The comms with Sofia was also excellent.
We would love to come back some time.
