We had a fabulous week in Valencia (May 2019). The locations of Joanna's apartment in Ruzafa is ideal for exploring the city. It's a 10-15 minute walk from the Metro & main train station and is only a 20 minute walk to the centre of Valencia (Central Market etc.).
The apartment itself is spacious (plenty of room for 4 of us) and very clean. The outside space is ideal for morning breakfast or an evening drink. The Ruzafa area has plenty of great restaurants & tapas bars and is a great area for a leisurely stroll exploring the boutique shops and eateries. The apartment is on a quiet street and is close to all amenities you could wish for supermarket, bike hire etc.
Communication with Joanna before and during our visit was excellent and I can highly recommend the apartment as a great base for exploring the beautiful city of Valencia.
