This hotel was better than expected. The rooms are clean, comfortable and even pool view room allows you to see a bit of the sea. It is a 3 stars, but had a small safe (no fee) and the toiletries are the quality of 4 stars. This place is the real Galicia, very few tourists from outside Spain (except Portugal) and it feels like the real northern Spain. The food was very good and the breakfast excellent. Even if you don't have a car, the summer connections of the bus (Monbus, from/to Pontevedra to/from O Grove via Lanzada beach) allows you to explore the zone quite well and the bus stop is in front of the hotel.
The service at the hotel is very good and everybody works hard to please you with a big smile.
The beaches few minutes down from the hotel are very nice and deserve exploring; the water is cold though and a wetsuit is advisable if you want to swim or snorkel.
If you want sun, good Galician hospitality, this is a lovely and quiet hotel to be based at. If you want to be in a busy town, I would recommend to book hotel in Portonovo or Sanxenxo (20 mins in bus from Vermar hotel).
