It is a very nice hotel in / near the centre of the city. The reception is very efficient (incl. a cash machine in the lobby). The rooms are clean and very wel equipped. The breakfast is excellent.
There is a bar next to the lobby open 24 hours a day. Near the hotel there are several restaurants and bars, but the hotel itself is a oasis of rest.

Stayed in the London Hotel in Odessa for 3 night for a friends wedding. Arrived with a group and check in swift and everyone was shown to their room.
They have a nice large lobby with plush seating. There is an ATM in the lobby. Just off the lobby is the Glaglow bar open 24hrs for drink and food. The barman wears a kilt, hence the name. Its a small bar, enjoyed making use of there late hours. The room service is 24 hrs also.
The room are large with a huge bed. Spotlessly clean as was the bathroom. Im not sure if they have non smoking rooms or not, but there was an ashtray in the room (clean of course).
Buffet breakfast with enough for any guests appitite. The dinning room is large and it was here that we had the wedding reception. The hotel allowed the Groom to bring his own drink for the entire wedding party of about 100, and it was served to us all night long. Not sure if this is the norm for Ukraine, but did make for a free bar and relaxed atmousephere.
Good location close to the city center and night life. The beach is a bit of a walk but manageable. Staff were helpful giving us a map of the city and directions to anywhere we needed, always seemed to be at least one who spoke good english.

Hotel is very nice and in a good location - 10 minute easy walk from downtown area and on a very quiet street overlooking a lovely park. A/C worked well, hundreds of channels on satellite TV (although most in Russian or, inexplicably, in Arabic). Room smelled a bit of cigarette smoke, but not too bad. I was not feeling well while at hotel and staff was extremely accommodating and kind. Service is reserved but good. I highly recommend for good value, not in the middle of the craziness yet extremely accessible to main tourist sites.

We just came back from an Odessa weekend trip where we staid at Hotel London.

The location of the hotel is not perfect, it's neither directly in the center nor at the beach.

The theme of the hotel is clear, "London". All the staff runs around in English costumes, all furniture is old English style (but mostly platic, artificial leather - and made in China), all paintings show some places in England. There're many flowers around, of course all plastic...

We did have a "Lux" room (which is the name for a two-room suite). The living- and bedroom has been okay (but a bit tasteless). But the bathroom has been completely tasteless, unpractical and not clean. Twice we found black hair (most propably of the cleaing lady) on the toilet and in the sink. The hair dryer has been useless (no power) and for new toilet paper we had to ask. All that at € 210.00 is too much!

Internet (WiFi) is at charge (€ 12/day).

Odessa offers far better options than Hotel London, i.e. Hotel Otrada, Continental etc.
